HOT-WATER HEATING APPARATUS- Specification of Letters Patent.

Patented April 17, 1906.

Application filed January 21, 1901. Serial No. 14,036.

To all whom it may concern.-

Be it known that I, THOMAS H. J ANE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hot-Water Heating Apparatus, of which the following is a full, clear, and exact specification.

This invention relates to improvements in hot-water heating apparatus in which the steam-heating system has been utilized for heating water for domestic and other uses; and it also relates to ap aratus in which a special heater or furnace as been employed for the same purpose, but between which and the steam-heating system there is no mechanical connection.

The prime object is to have a house-heating system so connected With a water-sup ly system and with a special heater there or that said special heater may be cut out of the water-heating system when the steam-heating system is employed for heating water and, on the other hand, that the steam-heating system maybe cut out when the s ecial heater is being used for that purpose, w 'le at the same time other devices common and essential to both when heating the water may be utilized for supplying water to and conducting it through the water-heatin system without regard as to which particu ar heater is being used at any time.

With these ends in View my invention consists in certain features of novelty in the construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafter appearing are at-,

tained, all as fully described with reference to the accompanying drawing and more particularly pointed out in the claims.

The figure illustrates in diagrammatic View and partlyin section, in side elevation a steam and water heating system embodying my invention.

1 indicates an ordinary furnace and generator for a steam-heating system for houses, inclosed within a shell or drum 2, from which project two steam-discharge pipes 3 and 4, respectively, both of which are to be connected in the usual manner with the pipes and radiators throughout the house to be heated, the water for steam being supplied from a city water system or other source of supply through a pipe 5, into which opens a return-pipe 6, through which the steam and condensations are returned from-the pipes 3 and 4 to the generator, the pipe 6 having therein an ordinary gooseneck trap 7.

Above and supported on the shell 2, but, it may be, by any suitable support, is a waterheating chamber 8, which for convenience of access, may be cylindrical, with its ends closed by screw-caps 9 10, respectively, and within this water-heating chamber is a convolute pipe and may be a coil 11, connected at one end with the steam-distributing pipe 3, neXt which it is provided with an ordinary stop cook or valve 12 for shutting off the supply of steam thereto when and for the pur oses hereinafter described the opposite and l bwer end of which coil 11 is connected with a bent pipe 13, which passes down inside the shell surrounding the furnace, thence horizontally out through its side and down to and near the bottom of the furnace where it is joined to the pipes, (not shown,) forming the usual steam-generator of the furnace, so that steam after passing from the pipe 3 through the coil 11 will be next subjected to heat of the furnace and then pass back into the generator thereof.

The water to be heated by the steam-coil 11 enters the water-heating chamber near its bottom and at one end through a horizontal branch of a pipe 14, the vertical portion of which extends downwardly to a point where it is connected with a horizontal pipe 15, in which is an ordinary valve 16 for regulating and, when desired, for cutting off the supply of Water to the water-heating chamber.

Pipe 15 by means of an elbow 17 is connected with the bottom of a water-tank 18, which, as shown, is a vertical cylinder closed at both ends, but may be of any other form and supported from a suitable edestal 19 or by any other ordinary means a apted for the purpose. p

Projecting downwardly in the water-tank 18 is a pipe 20, through which cold water or water at ordinary temperature is supplied from a city water system or other source through a pipe 21, connected therewith.

Hot water in the heater 8 discharges there from through a pipe 22, opening into the heater at the opposite end, from which water is supplied thereto and at a point preferably near the top of the heater, so as to best promote the discharge of hot water up through the pipe 22 through its tendency to rise.

Pipe 22 is connected with a horizontal pipe 23, which connects with the house system, through which the hot Water is distributed,

ICO

and said pipe 23 is also connected with the water-tank 18'by a pipe 24, opening in the upper part thereof and by which means when the house distributing system is not being discharged the water-tank becomes a storage vessel for hot water.

At the beginning of heating hot water discharged through the pipe 20 into the watertank 18 and with the valves 12 and 16 open the cold water passes through the elbow 17, thence through the pipes and 14, whence it discharges into the heating-chamber, and after being subjected to the heat of the coil 11, to which steam is applied directly from the pipe 3 of the steam-heating system, said heated water passes out through the pipes 22 and 23 to the water-pipe system of the house, and when this system is filled and not in use said hot water will pass from the pipe 23 down through the pipe 24 into the watertank 18, where it will remain until used unless through reduction in temperature it is again conducted back through the water-heater 8. In this connection it should be observed that the coil 11 takes steam from the hottest portion of the steam-heating system-that is to say, from the pipe 3directly after the steam discharges therein from the generator, and that after such steam has passed through the coil 11 it is subjected to the heat of the furnace before it again reenters the genera tor, and that when it does reenter its entry at such a point thereinthat is, near the bot- 'tomwhatever reduction in temperature, it

may have does not afiect the temperature of the steam discharging from the generator through the pipe 3.

At best,'owing to the location ofthe steamheater 8 at a point where it derives some heat from the furnace and to the arrangement of the pipes connecting the coil 11 with the generator in the manner described, there is practicall no condensation of steam even in the initia heating of the water and none whatever, as is demonstrated bypractice, after the water in the water-distributing system becomes heated to the'proper temperature for domestic purposes about a house.

Another feature of my invention is the means providing for the employment of what for convenience I term a special heater 25 and which is of the ordinary construction and heretofore employed for a water-heating system, but without any connection with a house-heating system? when both systems are simultaneous y employed.

Water-heater 25 is of the ordinary construction and has connected with its generator a pipe 26, opening into the tank 18 at a point above the bottom of the water-discharge pipe therein, said pipe 26being provided with an ordinary valve 27 for-regulating and for cutting off the flow of water therethrough. Near the bottom of the heater is a pipe 28, which connects with the pipe 15, through which water from the water-tank passes to the heater 8, and in this connection it is proper to add that the pipe 15 has no other connection with the heater 25.

When for any reason the steam-heating system is not in use, the valve 16 in the pipe 15 is closed and the valve 27 in the pipe 26 is opened, and as a result all of the water disc arging through the pipe 17 from the tank 18 passes through and is heated in the special heater 25, whence it discharges through the pipe 26 into the tank 18 and at a point above the discharge of supply-water therein and by this means is free to rise to the top of the tank and discharge thence through the pi e 24 into the house distributing- 1 e 23. lhen, on the other hand, the steam-heating system is in use, valve 27 in the pipe 26 is closed and valve 16 in the ipe 15 is opened, thus cutting out the special heater 25 and heating the water for domestic use entirely by means of the steam-heating system, as before described, and in this connection it; should be observed that when for any reason it is desirable to inspect or repair the water-heater 8 steam is s ut off from the coil by closing the valve 12, after which one or both heads are unscrewed, as may be desired or necessary.

In conclusion it should be borne in mind that the device described, and illustrated in the drawings is,'as before stated, merel diagrammatic and obviously that in its practical application and adaptation to various buildings numerous and various changes in theform and arrangement of the several pipes and parts will be necessary; but these changes in arrangement and form will not be a substantial departure from the spirit of my invention so long as means are provided by which asteam-heating system is utilized for heating hot water for domestic use without substantially reducing the efficiency thereof for house-heating purposes, and vice versa, and by which such a system will simultaneously produce hot water and steam-heat a house. i

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is

1. The combination with a steam-heating system and the generator thereof, of a waterheating chamber and means for heating the same by steam from said system, of a Water'- tank and means for discharging supply-water therein near its bottom, a ipe connecting the bottom of said water-tanli with the hot-water heater and a special heater between said tank and water-heater, which said heater is connected at its bottom with said pipe and at its top with the water-tank at a oint above the water-discharge therein an means for cutting said heater out of the water-circulating system, substantially as described.

2. The combination with a steam-heating system and a coil therein communicating with the'steam-discharge pipe of the generator and at its opposite end with the bottom of said generator, of a water-heating chamber inclosing said coil, a water-tank, a pipe connecting said water-heating chamber with the upper ortion-of said tank and with the hotwateristributing system, means for supplying water from said heater to said tank near one end thereof, a special heater connected with the water-tank at a point above the water-supply thereto and at its lower end with the pipe connecting said tank with the waterheater and means for short circuiting the communication of said special heater with said tank and for cutting the water-heater I 5 out of the water-circulating circuit when said (sipecial heater is in operation, substantially as scribed.
